I don't understand where you are setting this. At any rate, your security access is controlled by your role membership and the role-to-album table 'gs_Role_Album'. Check gs_Role to make sure your role has the desired permissions, then check gs_Role_Album to make sure your role is associated with the desired album.
Restart your web site after editing the table to purge the cache and force a fresh data load.
